Wash the apples, peel and core them and cut into small pieces. In a saucepan with a splash of water, about enough to cover the bottom, cook the apples for about 10 minutes, then puree. If you like, you can now add a little sugar or cinnamon.
Put the applesauce in glasses, either warm or cooled, as you like, spread the yoghurt on top, add a few raspberries and chopped walnuts. Drizzle with honey as desired.
